    False Positive FDG PET/CT Resulting from Fibrous Dysplasia of the Bone in the Work-Up of a Patient with Bladder Cancer: Case Report and Review of the Literature
    (KOWSAR PUBL, 2012-12-27) DANE, FAYSAL; Aras, Mustafa; Ones, Tunc; Dane, Faysal; Nosheri, Omid; Inanir, Sabahat; Erdil, Tanju Yusuf; Turoglu, Halil Turgut
    Fibrous dysplasia of the bone (FDB) is a common, genetic, developmental disorder with a benign course. FDB can be seen anywhere throughout the skeleton. It is usually asymptomatic and found incidentally on imaging studies that are performed for other purposes. Although whole body 18 F-flourodeoxyglucose PET/CT (FDG PET/CT) is widely used in tumor imaging, infections and benign pathologies like FDB may cause false positive results. Herein we report the case of a 48-year-old FDB patient with transitional cell carcinoma of the urinary bladder. Restaging FDG PET/CT showed multiple mild to moderate hypermetabolic bone lesions which were initially misinterpreted as bone metastases. In this case report, we aimed to guide physicians in evaluating bone lesions in cancer patients with FDB in the light of the literature.

    Mickey Mouse Sign on Bone Scan in the Monostotic Form of Paget's Disease Mimicking Osseous Metastasis
    (GALENOS YAYINCILIK, 2020-10-01) TUROĞLU, HALİL TURGUT; Kesim, Selin; Turoglu, Halil Turgut; Ozguven, Salih; Ones, Tunc; Erdil, Tanju Yusuf
    Paget's disease is a chronic benign bone disease characterized by excessive and abnormal bone remodeling. Monostotic Paget's disease accounts for only 20% of the cases, and the monostotic form involving the vertebra with the Mickey Mouse sign is very rare. Herein, we report a case of suspected bony metastasis in the second lumbar vertebra that was diagnosed as Paget's disease because of the Mickey Mouse sign on bone scintigraphy, and the diagnosis was confirmed by biopsy. Therefore, bone scintigraphy may provide a positive contribution to the diagnosis, and may help to avoid unnecessary biopsy in cases with specific signs and patterns.

    The clinical utility of 99(m)Tc-HMPAO SPECT in Fahr's disease
    (SPRINGER, 2008) GÜNAL, DİLEK; Ones, Tunc; Dede, Fuat; Gunal, Dilek; Ekinci, Gazanfer; Memis, Hatice; Erdil, Tanju Y.; Inanir, Sabahat; Turoglu, Halil T.
    Fahr's disease is a rare neurodegenerative syndrome, characterized by massive symmetrical intracerebral calcifications of the basal ganglia, dentate nuclei of the cerebellum, and the adjacent parenchyma. Computerized tomography (CT) is considerably more sensitive to detect these intracranial calcifications than other imaging modalities. The clinical, CT scan, and 99(m)Tc-D,L-hexamethylpropylene amine oxime (99(m)Tc-HMPAO) brain perfusion single-photon emission computerized tomography (SPECT) findings in a 42-year-old woman with Fahr's disease are reported, and the clinical utility of 99(m)Tc-HMPAO SPECT findings in Fahr's disease is discussed in this article. In conclusion, 99(m)Tc-HMPAO brain perfusion SPECT seems to be useful in the clinical approach to Fahr's disease, and may provide more specific and clinically relevant information when compared with anatomical imaging.

    Endotracheal metastasis of colon cancer on FDG PET/CT
    (WILEY, 2021) BOZKURTLAR, EMİNE; Filizoglu, Nuh; Oksuzoglu, Kevser; Ozguven, Salih; Bozkurtlar, Emine; Ones, Tunc; Erdil, Tanju Yusuf
    Although tracheal involvement of lung cancer is frequently seen, endotracheal metastasis of colon cancer is a rare entity. Since endotracheal lesion gives no symptom until tracheal lumen nearly occluded, the diagnosis of endotracheal metastasis could be challenging. F-18 fluorodeoxyglucose positron emission tomography/computed tomography may be crucial to detect this unusal distant metastasis of colon cancer. Herein, we report FDG avid endotracheal lesion that was confirmed as metastasis from colon cancer in 56-year-old female patient.
